Backstreet Boys are celebrating their 20th anniversary this year, and now they're all back together for a documentary. The five guys, Brian Littrell, Nick Carter, A.J. McLean, Howie Dorough and Kevin Richardson have hired Katy Perry's Part of Me 3D producer Stephen Kijak to direct the movie - that's said to tell everything about the "boy"band. "''We always wanted to make a film and now is the ideal time. With Kevin back, the fact that we are masters of our own destiny, a new album in the works and our 20th anniversary - it all adds up to being the right time to share our story", the group stated. The group are also working on a 20th anniversary tour and album. Interesting! We wonder how many fans are still out there - cause aren't they getting kinda old...?
